Brian Homerding b4b21d807e Add, and infer, a nofree function attribute
This patch adds a function attribute, nofree, to indicate that a function does
not, directly or indirectly, call a memory-deallocation function (e.g., free,
C++'s operator delete).

Eric Christopher cee313d288 Revert "Temporarily Revert "Add basic loop fusion pass.""
The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

Eric Christopher a863435128 Temporarily Revert "Add basic loop fusion pass."
As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Xin Tong 9d2a5b1cf7 Add argmononly attribute to strlen and wcslen, i.e. they only read memory (string) passed to them.
Summary:
This allows strlen to be moved out of the loop in case its argument is
not modified in the loop in LICM.
